  10. 10. United StatesWith a total of 208 billion kWh needed for lighting in American homes, we need the equivalent of 13 nuclear power plants just to meet residential lighting demand. 10

  24. 24. Environmental Sustainability 24
  25. 25. Environmental Sustainability Even “better” products can sometimes be very bad. 25
  26. 26. Environmental Sustainability Where are CFLs made? Not in the U.S., under strict environmental regulation. CFLs are made in Indiaand China, where environmental standards are virtually non-existent. 26
  27. 27. The Case for ConservationSaving electricity is cheaper than creating it. 27
  28. 28. The Case for ConservationThe less efficient the light, and the shorter its life, the more beneficial an LED lighting upgrade will be. 28
  29. 29. The Case for Conservation A 50% reduction in lighting electricity usage = An 11%  reduction in global energy use.  In the US lighting electricity use for residential and  commercial facilities combined equaled 535 billion kilowatt‐hours in 2009. 13.6% of overall electricity usage. Even with a 28% adoption rate for CFL’s, US Households  throw away 5.5 million light bulbs a day.   29
  30. 30. The Case for ConservationWhat about conserving…. 30
  31. 31. The Case for ConservationCompanies with more profits  can hire more… 31
  32. 32. The Case for ConservationPeople who have to spend less on electricity  to light their homes can buy more… 32
  33. 33. The Case for ConservationLighting upgrades are consistently rated as one of  the top 1 or 2 recommended measures for  conservation by energy auditors. Breakeven is generally under 36 months and often  under 12 months. Rebates and tax incentives can  reduce the breakeven point even further. Assuming a 10% net profit margin, a business that saves $1,000 a year in electricity has made the same  net affect as increasing revenue by  $10,000.  33
  34. 34. Case Studies & Examples National & Local 34
  35. 35. National Case StudiesReplaced nearly all incandescent and halogen lights with LED in over 8,000 stores in US, Canada, Europe & Asia.80% reduction in lighting energy consumption.$30/bulb savings per year equivalent savings of ½ barrel of oil in CO2. Reduced average stores energy consumption by 7%. Over 250,000 LED Lamps installed in total.  35
  36. 36. National Case Studies Replaced 25 parking lot lights.  58% reduction in electricity while  maintaining IESNA illuminance recommendations.  44,000 kWh savings in electricity  per year – an equivalent of 30.4  tons of CO2 removed from the  environment.  $15k in electricity and $10k in  maintenance savings per year. Project payback in 3 years.  36
  37. 37. Local Case StudiesReplaced 600 low pressure sodium street lamps throughout the city. Immediate savings of $3,000/month in electricity. Significant maintenance savingsBetter quality of light with reduced glare and light‐spill.12 year projected lamp life – 3x the original lighting. Project cost of $425,000. 37
  38. 38. Local Case Studies The first city in the valley to install  LED streetlights on a wide scale.  Approx. 25% of city lights  converted.  Expected to reduce energy  consumption by 42% ‐ equal to 853  metric tons of greenhouse gas  emissions being removed from the  environment.  Funding made possible by an  ARRA grant.  38
  39. 39. Local Case StudiesSwitched out lighting in six parking lots to LEDs. Expected to save $127,000 annually in energy and maintenance costs. 2,000 lights will reduce ASU’s annual energy consumption for parking lot lighting by 59%. A reduction of 1.5m kWh, saving the equivalent of emissions from 208 passenger vehicles.  39
  40. 40. What if?...…. we could reduce lighting electricity usage by 50%? 40

  44. 44. In the United States we could… Shut down 76 coal‐burning power plants. This alone would save 167 billion gallons of water use and 281 million tons of carbon dioxide from being released into the environment.  Source: U.S. Energy Information Administration (EIA) 44
